Larger and faster flocs form, significantly improving subsequent sludge dewatering. However, the addition of flocculants generally requires a flocculant dosing device. Existing pipeline-based flocculation reaction devices are generally large and lack a matching internal mixing reaction device, resulting in space consuming installation and poor reaction performance.

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] Refer to the attached Figure 1-4 A miniaturized pipeline flocculation reaction device includes a pipeline 1 with a reaction device provided in the pipeline 1. The reaction device includes two symmetrically arranged stirring components 4 and a drainage mixing component 5 located between the two stirring components 4. The stirring component 4 includes a circular frame 42 rotated by the thrust of the water flow and a plurality of equidistantly distributed force-bearing inclined fan blades 43 provided thereon. A feeding pipe 55 distributed in a ring shape is provided in the drainage mixing component 5. By providing the stirring component 4 with the same shape as the pipeline 1, the water flow in the pipeline 1 can be stirred in a stirring-like manner, thereby reducing the volume and fully utilizing the existing space of the pipeline while being able to mix the sewage and flocculant well.

[0018] It should be noted that the stirring assembly 4 includes a circular mounting platform 41 fixed in the pipeline 1, a circular frame 42 is rotatably connected in the circular mounting platform 41, and both ends of the drainage mixing assembly 5 are respectively connected to the two circular mounting platforms 41.

[0019] It should be further explained that a diversion assembly is installed at the water inlet end of the pipe 1, which includes a diversion head 6 and a plurality of circular pipes 7 connected end to end. The plurality of circular pipes 7 form a spiral waterway. The diversion head 6 includes a converging port 9 connected to the top circular pipe 7. The circular pipe 7 at the end is provided with a plurality of inclined drainage pipes 8. The inclined drainage pipes 8 and the inclined fan blades 43 have the same inclination angle. The drainage outlet of the inclined drainage pipe 8 is facing the inclined fan blades 43. Figure 1 As shown, the water inlet end of the pipe 1 is provided with a flange connected to the sewage pipe. When the pipe 1 is connected to the sewage pipe, the sewage entering the pipe 1 will first enter the converging port 9 and converge, and then form a spiral waterway through multiple circular pipes 7, thereby generating spiral kinetic potential energy, and finally be discharged from multiple inclined drainage pipes 8 directly to the inclined fan blades 43. Because the inclined drainage pipes 8 and 23 have the same inclination angle, the inclined fan blades 43 can be directly pushed with the maximum kinetic energy, thereby causing the circular frame 42 to rotate. The rotating circular frame 42 forms a stirring-like agitation on the sewage through the inclined fan blades 43, so that when the sewage enters the drainage mixing assembly 5, it can be well mixed with the coagulant.

[0020] In addition, in this embodiment, it should be noted that the drainage mixing component 5 includes a drainage column 51, a conical cavity 52 is provided in the drainage column 51, and threaded drainage grooves 53 are distributed in the conical cavity 52. ​​The drainage column 51 is provided with a feeding cavity 54, and the feeding pipe 55 passes through the threaded drainage groove 53 and is connected to the feeding cavity 54. Through this arrangement, after the water flows through the first stirring component 4, it passes through the conical cavity 52 to converge the water flow, and then the spiral water flow is diverted again through the threaded drainage groove 53. Even if the potential energy of the water flow has been reduced at this time, this potential energy is still continued through the diversion, thereby driving the circular frame 42 at the back to rotate, so that the sewage just mixed in the drainage mixing component 5 can be stirred in a similar manner to stirring, thereby further ensuring the mixing effect. A liquid infusion tube 3 is fixed outside the pipeline 1, and the liquid infusion tube 3 is connected to the feeding cavity 54, so that the coagulant can be input into the feeding cavity 54 through the liquid infusion tube 3.

[0021] In addition, in this embodiment, the pipeline 1 is connected to the filter pipeline 2 through a flange, and a filter device is provided in the filter pipeline 2. In this embodiment, the filter device is a common component in the field, and the contents not described in detail in this specification belong to the existing technology known to those skilled in the art.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of such features.
